OTH I only came to realize that I actually like duck typing in some situations when I tried to add type hints to one of my Python projects (and then removed them again because the actually important types consisted almost entirely of sum types, and what's the point of static typing if anything is a variant anyway).

E.g. when Python is used as a 'scripting language' instead of a 'programming language' (like for writing small command line tools that mainly process text), static typing often just gets in the way. For bigger projects where static typing makes sense I would pick a different language. Because tbh, even with type hints Python is a lousy programming language (but a fine scripting language).
